As human activities in the New World Tropics (Neotropics) increase in intensity and extent, so do the interactions between natural and human-dominated ecosystems. The essays in this book compare the sociocultural and biophysical aspects of managing the resource base in these regions. It describes the potential benefits--and liabilities--of the major food, fuel, and fibre production systems, each one exmined in terms of its potential impact upon resource preservation and utilization. The book is a departure from traditional treatments of agricultural sustainability or natural resources development in that it addresses the specific systems prevalent in the Neotropics, focusing on the flow between agricultural and natural ecosystems.
